A. Incorrect. Cardiovascular disease can impact kidney health. The heart and kidneys are closely connected, and conditions that affect the heart can also have implications for kidney function.

B. Incorrect. High cholesterol levels can contribute to cardiovascular disease, and cardiovascular disease is a significant risk factor for chronic renal failure. Therefore, high cholesterol indirectly impacts kidney health.

C. Correct. Cardiovascular disease, including conditions like heart failure or atherosclerosis, can lead to decreased blood flow to the kidneys, impairing kidney function and contributing to chronic renal failure.

D. Incorrect. High blood pressure is a well-established risk factor for chronic renal failure. Uncontrolled hypertension can damage the blood vessels in the kidneys, leading to kidney dysfunction over time.
